After her father's death, young Amiya Morgan travels alone to Riverside Zoo with a wooden lioness sculpture he left behind, searching for the mother she has never met. Along the way, she unexpectedly discovers she can understand animals.
Her father's only clue before dying was, "Your mother is there."
Inside the zoo, Amiya befriends a male lion named Stirling, a panda named Po, a white horse named Flash, and other animals. With their help, she searches for her mother step by step. Meanwhile, she gradually uncovers an illegal animal trafficking scheme hidden behind the zoo, and the dangerous Victor Crane is planning to secretly sell many rare animals. What surprises her even more is that Leona Grant, the zoo director who has been protecting her, is not only the mother she has been searching for, but also an undercover agent secretly investigating the criminal organization.
To protect her mother and the zoo, Amiya joins forces with her animal friends to fight Victor's scheme. In the end, the criminal gang is destroyed, the trapped animals are rescued, and Amiya is finally reunited with her mother, finding a true home of her own.
